Review: Best OHTO pen refill from Japan - Original quality ink refill from Japan. Came encased in the packing with seal and then additionally wrapped for shipment to preserve it well. The water based ink works well on most paper, of course more porous paper tends to feather the ink when writing, but it dries fast on denser paper as well. The color is a bold black which contrasts nicely on ivory or bleached papers. I tend to journal for hours and the special barrel contributes to its reliability and consistency. The .7 mm is my personal favorite as it has a balance between writing fluidity and changes in wiring style for more decorative writing.
Review: Refill - Fit and works just fine !

### ⭐⭐⭐⭐ good, not perfect.
*by A***R on January 11, 2026*

Im using this refill in a Tactile Turn standard side click pen. This refill is the perfect size for this pen, no trimming or taping necessary, no wobble from the needle, its a perfect fit. It glides smoothly on paper, and overall I would say this writes "OK". I am still on my first day using this refill, however I have had a couple instances where the ink skips, or will stop completely for about a word and a half while writing. I'm not sure if it needs a little bit of writing to break it in, but I would say that a high quality refill like this should be ready to go out of the gate. On a personal note, the ink is not as dark as others I have seen, although nothing that would impact legibility, just a lighter shade of black, maybe more like a dark graphite color. The packaging was excellent for this product, and I have no doubts this could be tossed into any sort of box or envelope and mailed without damage.
